'''UnKindness Of Ravens (UKOR)''' was formed in 1991
as a musical experiment with unconventional sound construction. While the large and often changing ensemble uses some traditional instrumentation, the bulk of its sound comes from self-constructed instruments—often created much like its music, in Surrealist automatism|surreal automatic style
shifting as the course of play dictates. While it may most appropriately be grouped with noise music
or musique concrète
, the ensemble sometimes describes itself as "musical scribble." This term comes from its method of recording and composing. UnKindness Of Ravens always records its music first and composes its songs second. The group's core team Joshua Chalifour and Michael Keigher treat the recordings as sound palettes for composing the albums.
